Abstract: A method includes casting a metallic material (56) in a mold (20) containing a core, the core having a substrate (40, 44) coated with a coating (42). A removing of the metallic material from the mold and decoring leaves a casting having a layer formed by the coating. The coating has a ceramic having a porosity in a zone (50) near the substrate less than a porosity in a zone (52) away from the substrate.

Abstract: A method casts a plurality of alloy parts in a mold (600; 700) having a plurality of part-forming cavities (601). The method comprises pouring a first alloy into the mold causing: the first alloy to branch into respective flows along respective first flowpaths (676, 684; 708) to the respective cavities; and a surface of the first alloy in the part-forming cavities to equilibrate. The method further comprises pouring a second alloy into the mold causing: the second alloy to branch into respective flows along respective second flowpaths (676, 680; 712) to the respective cavities.
Abstract translation: 一种方法是在具有多个部件形成腔（601）的模具（600; 700）中铸造多个合金部件。 该方法包括将第一合金浇注到模具中，使得第一合金沿着相应的第一流路（676,684; 708）分支到相应的流中到相应的空腔; 以及部件形成腔中的第一合金的表面平衡。 该方法还包括将第二合金浇注到模具中，使得第二合金沿相应的第二流动路径（676,680,712）分支到相应的流体到相应的空腔。
